Title: Improvements in Dental Pluggers.
Inventor: INGLEHART WALTER ANDREW
Filed: 1898-07-23
Granted: 1899-06-24
Abstract: 16,134. Lake, H. H., [Inglehart, W. A.]. July 23. Dental instruments.- A dental plugger consists of a rod 2 mounted free to slide in a sleeve 4 screwed to one end of a cylinder 1 and in a sleeve 5 secured to the other end of the cylinder by a disc 6 engaging the turned-over end 7 of the cylinder. Surrounding the rod 2 is a sleeve or hammer 3, which is pressed downwards by a spring 11 carried between a nut 9 on the sleeve 5 and a lock-nut 21 for a sleeve 17 secured to the sleeve 3. Projections on the nut 9 engage slots in the cylinder 1, so that the rotation of the sleeve 5 adjusts the tension of the spring 11. A spring- actuated piece 13 mounted in a slot in the rod 2 is formed with a pawl 14, which engages the sleeve 3 and, on pressure being applied to the rod, forces it upward until a roller 16 on the sleeve 4 engages a cam 15 on the piece 13 and releases the sleeve 3, which is forced downward by the spring 11 until the sleeve 17 strikes against a pin 18 on the rod 2 and drives the latter downward. A spring 19 forces the rod 2 downwards until the hammer is again engaged by the catch 14. A tip 22 limits the motion of the rod. The cylinder 1 is enclosed in a rubber or other tube 24, caps 25 and 26 securing it in position. In a modification, the rod 2 does not extend quite through the sleeve 3, in which case the end of the latter strikes on the top of the former.

Granted: 1901-06-08
Abstract: 7292. Birkbeck, H., ["Steamobile Co. of America"]. April 9. Feedwater, controlling ; fires, extinguishing a n d checking when water is low.-Relates to means for automatically regulating the waterlevel in a boiler and the supply of fuel to the burner. The application to the steam generator of a motor road vehicle is shown in elevation and section in Figs. 1 and 2 respectively. The feedwater is forced by the pump D from the tank B into the boiler A, except when a valve G in the shunt-pipe F is opened, in which latter case the water passes back to the tank. The valve G is operated from a float-ball 15 by means of the crank 20, lever 19, and calliper-shaped arms 21 pivoted on the shaft 17. As the float-ball rises in the chamber 10, which is connected to the boiler by pipes 13, 14, it moves the arms 21 and opens the valve G, and as the float-ball falls it moves similar arms 23 which, by means of the lever 25, closes a fuel-supply valve 27 of the gasoline or similar burner H.

Title: Improvements in Alternating Current Electricity Meters.
Inventor: CATENHUSEN FRIEDRICH LUDWIG
Filed: 1901-07-17
Granted: 1901-11-23
Abstract: 14,562. Catenhusen, F. L. July 17. Energy meters.-A motor meter for a single alternating current has a conductive disc c revolved by the co-operation of a horse-shoe shunt electromagnet b with a main current coil d, which has no iron core and is placed at some distance from the spindle. The electromagnet b has two equal coils i, i<1>, connected in series between the mains, and such that the iron is not magnetized so high as the bend in its magnetization curve. The main current coil d consists of a few large turns, and is separated by a conductive plate from a coaxial fine wire coil g. The coil g is connected in series with a non-conductive resistance between the mains, and the point of connection between the coil g and the resistance is joined by a second resistance to the connection between the coils i, i<1>. The arrangement is such that the coil g co-operates with the magnet b to produce a resultant magnetic field in quadrature with the field due to the main current coil d, when the load is non-inductive. One of the two resistances may be inductive, and that in series with the coil g may consist partly of aoother coil acting on the disc. Two or more sets of coils may be provided to act on one disc, as described in Specification No. 14,614. A.D. 1898. A metal piece o serves to neutralize the effect of inequality of the windings i, i<1>. The invention is based on that described in Specification No. 18,789, A.D. 1900. The main objects are to obtain a large constant brake effect from the electromagnet b, and a long range of proportionality between the main current and the velocity of the disc.

Abstract: 18,187. Ellis, W. F., and Davis, E. C. Sept. 12. Suspension or tension wheels ; felloes or rims; spokes; tyres, elastic other than pneumatic.-Relates to cushioned tyres, to rims therefor, and to spoke nipples which allow a wire spoke to be easily inserted or replaced. In the form shown in section in Fig. 2, the rubber tyre 19 bears on the side flanges 40 of the wooden rim 17, and has side flaps lined with canvas 20 adapted to be cemented to the rim. The edges of the side flaps may be laced together, and they are covered by a shield 18, which may completely cover the side flaps and which may have wires enclosed in its edges. A leather cover may be shrunk on to the rim between it and the tyre. The rim is transversely divided at one place 41, Fig. 9, and the part on one side of the break has a lug 33 carrying a rack 29, which gears with a pinion 30 held in abridge bearing 32 on the other part. The two parts can be relatively adjusted by rotating the pinion 30, which is afterwards locked by screwing-up the nut 34. The outer end of each spoke 16 screws into a headed sleeve 28, which rotates in a collar 27 screwing on to a headed socket 26. The socket and collar have preferably left-hand threads and the sleeve right-hand, and the socket is prevented from rotating by flatted parts which engage with a correspondingly-shaped hole in a long washer 25 lying in the rim. An elastic band 22 passes over the head of each socket, and tends to hold the socket in its position nearest the centre of the wheel.

Abstract: 18,879. Connett, A. N. Sept. 21. Electric railways and tramways with conductors below the vehicles in a conduit or on the surface. Relates to means for raising the collectors and for shifting them laterally when the conduit is brought from the centre to the side of the road, and also to means for changing the connections in mixed systems with overhead and surface or underground conductors. Collectors.-The head H of the collector P slides laterally to the vehicle on the guides G<2> to follow the conduit. To lift the collector, its head engages one of the blocks L, which are raised in the angle guides G by chains C. The side chains C are mounted on sectors W<3> with chains on their axles connected to a ratchet-and-pawl holding and lifting device. The central chain C, fixed at C', passes round a pulley W<1>, which can be drawn back by a screw-and-nut gear M, N, and then past the guidepulleys W<2>, W. A catch A may hold the nut N when the collector is raised, and the screw M may be worked by the removable controller handle X. Adjustable tappets F, F on the rod E are struck by the nut N near the ends of its travel, to operate a switch I which serves to connect the motors 0 to the collecting.shoes S or to the trolley T and earth, according as the collector P is down or up. If the conduit is central all the way, the collector is fixed to the central chain C, the other parts being omitted, but, if they are used, the flexible head D is suspended from a slide k movable between stops k<1> on the rods b.

Granted: 1902-01-16
Abstract: 23,141. Schlarb, L. M. June 3, [date applied for under Sec. 103 of Patents &c. Act, A.D. 1883]. Preserving meat.-Consists in curing ham, bacon, and other kinds of meat by (1) injecting brine and carbonic acid under pressure, (2) exhausting the air from the meat, and (3) treating it with brine in vacuo. In some cases the .meat is subjected to a final treatment with carbonic acid under pressure. A closed tank 2, Fig. 1, is first filled with brine, and carbonic acid, admitted from a reservoir 14 until the brine is under a pressure of about two atmospheres. The brine, impregnated with carbonic acid, is then injected into the meat by means of one or more nozzles 13, having valve connections with the tank 2. When sufficient meat has been injected, it is placed in a chamber 18, Fig. 2, under a grating 24, and, after closing this chamber, the air is exhausted through the pipe 27. Brine is then admitted through the pipe 20 from a reservoir 19, and the meat is left in the brine for about 10 hours. Where the meat is to be exported, the brine may be drawn off from the chamber 18, and the meat subjected to a final treatment with carbonic acid under pressure.
